It shouldn't exist, that's fine.

It's a detection problem. Mesa is supposed to read GPU info and find 
out that
the driver is actually radeonsi_dri.so, not the nonexistent 
amdgpu_dri.so.

You can try setting the environment variable 
MESA_LOADER_DRIVER_OVERRIDE=radeonsi
as a workaround, but this really shouldn't happen.

Have you tried not having an xorg.conf at all?

Or install xf86-video-amdgpu and configure it in xorg.conf:

Section "Device"
        Identifier "Card0"
        Driver "amdgpu"
        Option "AccelMethod" "glamor"
        Option "DRI" "3"
        Option "TearFree" "true"
EndSection

Well that's not fine.

Do GL applications use the GPU, at least?

Try running:
MESA_DEBUG=1 LIBGL_DEBUG=verbose glxgears
